ALSA: vxpocket: Fix invalid endian conversions

BugLink: https://bugs.launchpad.net/bugs/1792340

commit 3acd3e3b upstream.

The endian conversions used in vxp_dma_read() and vxp_dma_write() are
superfluous and even wrong on big-endian machines, as inw() and outw()
already do conversions.  Kill them.
